The tongue-in-cheek livery of South African airline Kulula includes a "This way up" sign on one plane and points out the locations of key components on another (+ slideshow).

Kulula's lime green Flying 101 aeroplane is covered in text explaining what each of its parts is called and white arrows pointing to where they are located.

The titles of the aircraft parts are accompanied by comical comments written beside them in brackets.

"This plane was designed in-house by our graphic design team as part of our bigger strategy to demystify air travel and explain some of the unknowns around air travel and flying," the airline commented.

Seats adjacent to the emergency exits are highlighted as the "throne zone" due to their extra leg room and the plane's registration number is dubbed its "secret agent code".

Features not visible from the outside such as seats, overhead compartments and toilets (noted as "mile high club initiation chambers") are marked out in dotted lines.

The graphics were designed for Kulula in 2010, along with a design for a Boeing 737 that has a "this way up" graphic painted in green along the side of the white plane.
